Lawn Sprinkler System Winterization


Winter Shut-Down Service

Although we live in Beautiful BC, we still experience freezing temperatures. Annual Winter Shut-Down Service is recommended to protect your irrigation system.

To minimize the risk of freeze damage to your irrigation system, you’ll need to “winterize” it. Our service technicians begin during the last week of September through to the first week of November. We winterize your sprinkler system by turning off the isolation valve at the main connection. The technician then blows out the water through all the piping, valves, and heads with a suitably sized air compressor (185 CFM). If we miss seeing you and have no access to your panel, we “bleed” the solenoid valves from outside. In this case, please ensure that you put your controller in the OFF position or RAIN position for the winter. It is advisable to install a surge protector. This will protect the unit from surges and power outages. If your surge protector is blinking, it has been “hit” and needs replacing.

In order to ensure that we get to your system before the first cold snap, we ask that you sign up in advance for our Winter Shut-Down Service.


Please note: Any system that is leaking badly from the main connection, main line, or valve manifold must be repaired before winterization service can be completed. Repairs will be advised and quoted.
